Former NFL star Aqib Talib's brother, Yaqub Talib, is a wanted man in Texas -- this after cops say he was involved in a fatal shooting at a little league football game this weekend.
The Lancaster Police Department fired off an announcement Sunday saying that they were looking for Yaqub in connection to the death of an adult male Saturday ... who was shot and killed during an argument at the conclusion of a match that parents were angry about.
The man is said to be a coach for one of the teams .
